Abstract:
Disclosed herein is a method of producing 4-fluoroethylene carbonate, in which ethylene carbonate reacts with a mixture of fluorine and nitrogen gases. The method comprises feeding a mixture gas of fluorine gas and nitrogen gas into a reactor having ethylene carbonate charged therein, so as to react the ethylene carbonate with the mixture gas of the fluorine gas and the nitrogen gas. The mixture gas fed in the reactor is regulated to have a desired bubble size while passing through a gas bubble regulating column, in which a packing for a packed column is packed. In the method, EC directly reacts with F2/N2 mixture gas to produce FEC, thus a purification process is simple and it is possible to produce FEC at high conversion efficiency and selectivity.

Abstract:
A method for removing impurities grown on a phase shift mask. The method can advantageously control growth of impurities by further performing HF cleaning and baking after cleaning to minimize the amount of residual chemical ions generated during cleaning. Specifically, the method comprises forming a phase shift mask pattern including a phase shift film and a light-blocking film on a quartz substrate, cleaning the phase shift mask pattern formed on the quartz substrate using a solution containing sulfuric acid ions or ammonium ions, cleaning the cleaned phase shift mask pattern using an aqueous HF solution, and baking the phase shift mask pattern cleaned with the aqueous HF solution.

Abstract:
An apparatus and a method for reproducing a MIDI file are provided. In the apparatus and the method, a point that limits reproduction of a MIDI file is determined and reproduction of the MIDI file is forcibly terminated at the determined reproduction limitation point when the MIDI file is reproduced. Therefore, non-continuous points are reduced and thus noises are reduced, so that the MIDI file can be reproduced in high quality.
Abstract:
The present invention relates to a plasma display apparatus and an image processing method thereof in which when the plasma display apparatus is driven, a picture quality is prevented from being degraded due to a line load. The plasma display apparatus for processing input video data to display an image, the apparatus includes: an inverse gamma correcting unit for correcting the video data into a previously stored gamma data, and linearly converting luminance depending on a gray level of a video signal; and a line load processor for compensating for a decreased amount of the luminance depending on an increase of a line load of a picture, which is displayed using the video data inputted from the inverse gamma correcting unit. The present invention compensates for the decreased amount of the luminance of the input video data, thereby reducing a line load effect.

Disclosed are methods of fabricating a semiconductor device, by which the pad and fuse layers play their roles smoothly and to enhance a quality of a final semiconductor device. According to one example, a disclosed method includes forming an insulating layer covering a pad and a fuse on prescribed portions of a substrate, simultaneously forming a first trench exposing an anti-reflective coating layer provided as a top layer of the pad and a second trench having a portion of the insulating layer underneath over the fuse by selectively removing the first insulating layer, filling up the first and second trenches with an etch rate adjustment layer, exposing the anti-reflective coating layer to leave a portion of the etch rate adjustment layer within the second trench by selectively removing the etch rate adjustment layer, and simultaneously removing the anti-reflective coating layer and the portion of the etch rate adjustment layer from the second trench.

Discloses herein is a method and apparatus for processing video data of a display device in which dithering noise generating when a motion picture is displayed can be minimized. According to the present invention, the method of processing the video data of the display device includes the steps of comparing data of an ith frame (i is a natural number) and data of a (i+1)th frame to determine whether the data of the (i+1)th frame is a motion picture or a still image, and employing a different dithering method depending upon the determination result of the motion picture or the still image.
